JAMES HARRISGN IVIARTIN, OF LOS ANGELES, CALIFORNIA.

WAVE-MOTOR.

Application filed August 13,1919.

To all whom it may concern:

Be it known that I, JAMES H. Man'rn i, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of Cahforma, have invented certain new and useful Improvements in Wave-Motors, of which the followingis a specification.

My invention is an improvement 1n wave motors, and the invention has tor its ob ect to provide a simple, inexpensive but eiiicient motor of the character specified, composed of units which may be arranged 1n batteries, to provide a machine of any capacity wherein the intermittent movement of the waves is transformed into the continuous movement for power purposes.

In the drawings:

Figure 1 is a side view of one ot the units,

Fig. 2 is a top plan view of a battery of four, 7

Fig. 8 is a side view of the mechanism for transforming intermittent movement into continuous movement,

Fig. 4 is a front view,

F 5 and 6 are sections on the lines 55 and 66 respectively of Fig. 1,

Fig. 7 is a top plan view showing a preferred arrangement of units.

In the present embodiment of the invention the machine is composed of simllar units, which may be arranged in batteries of four, six or any other number of unlts, to provide a machine of the desired capac ity. The units are preferably arranged in pairs, the members ofeach pair being on opposite sides of a suitable support 1, and each unit consists of a pair of beams 2 and 3, which are pivoted to the support in spaced parallel vertical relation.

Each lever has oppositely extending journal pins 4 at its center, and these journal pins are journaled in sectional bearings 5 on the support. The upper end of the beams 2 and :3 are connected by a link or guy 6, and the lower end by a similar link or guy 7,

the arrangement being such that the beams must swing together. Connected with the lowerend of the beam 2 is a weight 8, each weight being adjustably connected with the beam as shown.

On the lower end of the beam 2 there is rovided a tubular casing 9, and in this casing a rod 10 is mounted to be adjusted vertically, and to be held in adjusted posi- Specification of Letters Patent.

weight 8, which together with the beam constitutes a pendulum. The counter weight 8 has laterally extending vanes 17, which are adapted to receive the force of the moving water of the wave to swing the pendulum.

The unit or units are arranged in the manner shown in Figs. 1 and 2, in such position that the moving waves will impinge against the vanes of the elements 8. In shallow water there is movement of the water in wave motion, and this movement will carry. the vanes toward and from the shore, so that the beams 2 and 3 will be swung in opposite directions.

The movement of the beams is transmitted to a shaft 16 j ournaled on the supports 1 for the units, in sectional bearings 18, and this shaft carries a pulley 19, which is connected by a belt 20 with a pulley 21 on a driven shaft 22. This shaft 22 is also journaled on the supports 1, in sectional bearings 23, and it carries a flywheel 24 from which the power may be taken.

A pair of grooved pulleys 25 is arranged on the shaft 16 at each support 1, the members of the pairs being on opposite sides of the support. The pulleys 25 are loosely mounted on the shaft, and between each pair is secured a ratchet wheel 26, and each pulley has a pawl 27 pivoted thereto, and engaging the ratchet wheel.

The upper end of each beam 2 and 3 is connected to a pulley 25 by flexible members 28 and 29, as for instance a cord or cable. Each of these flexible members has its ends connected to the beam, and its intermediate portion is coiled once about the pulley, to insure a firm grip of the cable on the pulley.

In operation, the improved motor is composed of sufiicient units, as for instance multiples of six. The beams 2 and 3 are set approximately 60 ft. apart on a pier under which the tide comes in both at low and high tide. The element 8 is of relatively great weight, so that when the wave or breaker drives it shoreward and upward it will return to vertical position of its own weight. The flexible cables may be wrapped more than once about the pulleys if desired, and they are taut, so that they will turn the pulleys under the movement of the waves. The waves are at intervals of A0 to 80 ft., and by placing the units at 60 ft. with six units there is generally push or pull of from 2 to 3 units 011 the shaft at one time.

In Fig. 7 is shown a preferred arrangement of the units, a battery of four being shown. It is obvious that many arrangements might be made, depending upon conditions and purpose to be served. The broad idea of the invention is a central shaft on which all of the sheaves are journaled and all ratchets made rigid. Two sheaves and two ratchets are placed directly between a walking beam and a pendulum, and a flexible cable wrapped in reverse direction, and sheaves l and 2 connected to the top end of pendulum and beam so that the action going and coming will be in one direction. One beam and a connected pendulum together with a cable and ratchets is a unit.

I claim:

1. A wave motor composed of a series of wheel secured to the shaft for engagement by the pawl, and a flexible connection for each beam having its ends connected with the beam at the upper end thereof, the intermediate portion winding upon the pulley.

2. A wave motor unit comprising a pair of beams arranged approximately vertical in spaced relation and connected at their lower ends to constrain them to swing together, a shaft, a driving connection between the upper ends of the beams and the shaft for driving said shaft in one direction when the beams are swung, and a counterweight having vanes slidably mounted on the lower end of one of the beams, and means for holding the weight in adjusted position.
